The sum of 555 consecutive integers is 270270270. What is the second number in this sequence?
Simora [160]

The second number in the sequence will be 53.

<em><u>Explanation</u></em>

The <u>difference between any two consecutive integers is always 1</u>.

Suppose, the five consecutive integers are:  n,  n+1,  n+2,  n+3 and  n+4

Given that, their sum is 270. So, the equation will be......

n+(n+1)+(n+2)+(n+3)+(n+4)=270\\\\ 5n+10=270\\\\5n=270-10=260\\ \\ n=\frac{260}{5}=52

Thus, the second number in the sequence will be:  n+1= 52+1=53

Elina [12.6K]

Answer:

X=20Tan(25)

Step-by-step explanation:

So because the cat is looking at the tree it is a strait line making a right triangle with the tree. The cat spots the bird 25 degrees up in the tree making a triangle. Then use SohCahToa, and because u have the adjacent side use Tangent because you are missing the opposite side of the angle. There are a few other ways to find it but that is the simplest way to perform this, GOOD LUCK!
